title: [Impact of the application of the American Thyroid Association criteria on the diagnosis of hypothyroidism in pregnant women in Vigo, Spain].
abstract: In order to determine the impact of the application of the American Thyrold Associations (ATA) criteria for the diagnosis of hypothyroidism in pregnant women in the health district of Vigo, Spain, concentrations of serum thyrotropin (TSH), free thyroxine (T4L) and anti-thyroid antibodies were analyzed, comparing the frequency of pregnant women diagnosed with hypothyroidism and applying the criteria used in the hormone laboratory at Xeral Hospital and referential criteria established by ATA. The application of ATA referential criteria increased by 29.6% the number of female patients diagnosed with hypothyroidism. The application of ATA guidelines had an impact on the measurement of TSH concentrations in pregnant women, which calls for an evaluation of referential values of TSH based on the population and the local diagnostic methods.
